Description

a single-tube tower

technical field

The invention belongs to the technical field of disaster resistance and energy consumption, and relates to a supporting structure.

Background technique

The single-pipe tower structure is widely used in the supporting structure of electrical facilities such as power transmission, communication, and lighting. Most of the existing single-pipe towers are made of rigid structures with poor energy dissipation capacity. When the snow load, earthquake, strong wind, broken line load or impact load caused by a car accident exceeds the design, the single-pipe tower is prone to breakage. As a result, cascading damage of transmission lines or damage to communication and lighting facilities will be caused, which will easily cause catastrophic consequences such as large-scale power outages or long-term interruptions of communication and lighting. In addition, the conventional single-pipe tower is made in one piece. Once the local structure is damaged, it is difficult to repair only the damaged area. It is often necessary to replace the entire single-pipe tower structure, which not only reduces the service life of the single-pipe tower, but also Prolonged maintenance time, increased maintenance costs.

To achieve the above object, the solution of the present invention is:

The invention provides a single-pipe tower, which includes a base part and a main body part joined to the base part, and also includes a protection device hooped at the junction of the base part and the main part. As for the safety board, two safety boards are detachably spliced at the junction, and the shape of the space formed by the inner side of the spliced two safety boards is consistent with the three-dimensional shape formed by the combination of the base part and the main body part.

The above two insurance boards are spliced together by the first bolt group, and each insurance board is composed of an upper part, a middle part and a lower part, and the middle part is made of a material with a lower rigidity than the base part and the main body part.

The upper part, the middle part and the lower part are integrally formed during manufacture, or the middle part is respectively connected with the upper part and the lower part through the second bolt group, or the middle part is welded with the upper part and the lower part respectively. Further, several hollows are opened in the middle, and the hollows extend in the circumferential direction of the cross section of the safety plate. Furthermore, the shape of the hollowed out part is any one or more of circles, rectangles, rounded rectangles, prisms, and polygons.

The major axes of all the bolts in the first bolt group and the second bolt group are perpendicular to the central axis of the single-pipe tower. The above-mentioned main body is made of reinforced concrete, prestressed reinforced concrete or steel and other materials to make a rod-shaped or tower-shaped hollow structure. The above-mentioned base part is formed by pouring reinforced concrete, its bottom is buried in the ground, and its top is higher than the ground.

The three-dimensional shape of the main body part is one of prism or cylinder, and the three-dimensional shape of the base part is one of inverted cup shape, prism or cylinder. The above-mentioned main body part and the base part are joined by an arc-shaped surface at the junction.

Owing to adopting said scheme, the beneficial effect of the present invention is:

In the single-pipe tower of the present invention, firstly, the two insurance plates with mirror-image symmetry are made of materials with better energy dissipation capacity, economic benefits and less rigidity than the main body and base of the single-pipe tower. When the single-pipe tower is spliced on the single-pipe tower, once the external load on the single-pipe tower exceeds its design load, the insurance board will buckle accordingly, and at the same time, it will partially offset the energy of the external load, so the single-pipe tower can be guaranteed. The overall structure will not be destroyed.

Secondly, the two insurance boards are hooped at the joint between the main body and the foundation of the single-pipe tower and spliced together by multiple bolts, which can be easily disassembled from the single-pipe tower. After the buckling of the previous insurance board, only need Removing it and replacing it with a new safety plate can play a protective role again, so it can avoid replacing the entire single-pipe tower, which is conducive to the rapid repair of the partially damaged structure of the single-pipe tower, thereby effectively saving maintenance costs. It solves the problem that the current single-pipe tower needs to be replaced as a whole when it is partially damaged, and has important engineering significance for improving the reliability and repair efficiency of transmission lines, communication facilities, and lighting facilities.

Detailed ways

The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

Embodiment one

This embodiment is described by taking a transmission pole used in a power transmission system as an example. As shown in Figure 1, Figure 2 and Figure 3, the transmission pole involved in this embodiment is an application form of a single pipe tower in a transmission line, and is often used as a supporting structure for a transmission line 10, including a base part 9 , The protection device of the main body 8 and the ferrule at the junction 12 of the base 9 and the main body 8 .

As shown in FIG. 4 , FIG. 5 and FIG. 6 , the foundation part 9 is made of reinforced concrete, prestressed reinforced concrete or steel as a solid structure, its bottom is buried under the ground 11 and its top is exposed to the ground 11 . The shape of the bottom of the base part 9 is a platform, the three-dimensional shape of the top is a cylinder whose cross-sectional outer diameter gradually increases from top to bottom according to a certain trend, and the shape formed by the top and bottom is an inverted cup shape. In addition, in order to be consistent with the main body 8, the three-dimensional shape of the base part 9 can also be a prism or a cylinder, etc., and the three-dimensional shape of the base part 9 can be changed according to the actual needs of the single-tube tower. The top of the top of the base part 9 is a concave surface that is sunken toward the bottom, and the concave surface is in contact with the main body part 8 . The direction of the concave surface parallel to the transmission line 10 is less constrained than the direction perpendicular to the transmission line 10, so that the main body of the transmission pole 8 only deflects along the direction of the transmission line 10, preventing cascade damage of the transmission line. The foundation part 9 can excavate the foundation pit on the spot, then make it with reinforced concrete on-site pouring, and also can be transported to the scene after being prefabricated in the factory and directly placed in the foundation pit.

The main body part 8 is located above the base part 9 and is made of reinforced concrete or prestressed reinforced concrete to form a hollow structure. The local structure at the bottom of the main body 8 is made solid, which is to prevent local damage at the contact between the main body and the base. The three-dimensional shape of the main body 8 can be a prism, a quasi-cylindrical or a cylinder. In this embodiment, a quasi-cylindrical whose cross-sectional outer diameter gradually increases from top to bottom according to a certain trend is adopted. The general trend is consistent. The top of the main body 8 is pulled with a power line 10 , and the bottom end of the bottom is a convex surface matched with the concave surface at the top top of the base part 9 . The outer diameter of the convex surface at the bottom of the main body part 8 is equal to the concave surface at the top of the base part 9, and the above-mentioned joint 12 is formed after joining. The direction of the convex surface parallel to the power line 10 is less constrained than the direction perpendicular to the power line 10 . The relative lengths of the main body part 8 and the base part 9 are calculated in advance, so that the junction 12 is just a vulnerable part of the transmission pole. The body part 8 and the base part 9 are joined by arc-shaped surfaces such as convex and concave surfaces, which has the beneficial effect of enabling the body part 8 to deflect along the direction of the transmission line 10 . The main body 8 is prefabricated in a factory, and the manufacturing method is similar to the existing concrete rod manufacturing method.

As shown in Fig. 7, Fig. 8 and Fig. 9, the protection device used for the above-mentioned power transmission pole is used to protect the respective structures of the main body part 8 and the base part 9 through buckling energy dissipation and can be easily disassembled from the joint 12 and replaced. , including two safety plates 1 and a first bolt group 2 whose structures are mirror-symmetrical.

The insurance board 1 is manufactured in the factory to have an omega-like cross-section. During installation, the two insurance boards 1 are spliced together at the joint 12 between the base part 9 and the main body part 8 of the power transmission pole and installed and fastened with the first bolt group 2 . The long axis direction of each bolt in the first bolt group 2 is perpendicular to the central axis of the power transmission pole and parallel to the extension direction of the power transmission line 10, so that the main body 8 can be guided along the power transmission line under the action of a relatively large external load. The extension direction of 10 is offset. After splicing, the outer diameter of the cross-section of the space enclosed by the inner surfaces of the two insurance boards 1 gradually increases from top to bottom according to a certain trend, and the increasing trend is consistent with the increasing trend at the top of the base part 9. Therefore, after splicing The shape of the space formed by the inner surfaces of the two safety panels 1 is consistent with the three-dimensional shape formed by the combination of the base part 9 and the main body part 8 respectively. The extension length of the safety plate 1 along the direction of the single-pipe tower is determined according to the actual situation of the single-pipe tower to ensure that it has sufficient buckling energy dissipation capacity.

Each insurance board 1 is composed of an upper part 3 , a middle part 5 and a lower part 4 . The upper part 3 and the lower part 4 are also integrally formed with the middle part 5 during manufacture, and they are all made of materials such as steel with good energy dissipation capacity, economic benefits and less rigidity than the base part 9 and the main body part 8 . In this way, once the external load on the main body part 8 exceeds its design load, it will cause the main body part 8 to deflect relatively to the base part 9 at the junction 12, and the two safety plates 1 will buckle to offset the load carried by the external load. Part of the energy will not cause accidents such as collapse of the main body 8, thereby protecting other parts of the transmission pole from damage.
